Ghostbusters rpg resources are few and far between on the web.
Here are a few GB resources that I thought Ghostbusters rpg GMs might find some use for.

GB RPG Campaign sites:
Unholy Toledo

More like the rpg as published than Resurrection but a good example of using the local environs for your franchise setting.

MISC.
A lost addendum article to the Tobin’s Spirit Guide supplement is included in this 1989 pdf magazine ($1.99).
It has four additional ghosts:
1. Spirit Sword, a bloodthirsty possessed weapon/ectoplasmic weapon
2. Offenguffen, a elemental possessor spirit who embodies the spirit of Sloth
3. Badajoz, a kind of odd funerary guardian who acts up when funerary rights aren’t done properly
4. Mouldenkurdl, a spirit of material corruption who specializes in food

Ghostbusters: Prima Official Game Guide (usually $2.00 or less used)
This guide to the game has well written illustrated entries on the gear and Tobin’s spirit guide entries from the video game as well as the usual maps. It is almost a sourcebook to the video game but not quite, still at two bucks you don’t have much to lose. Most if not all these entries are available for free but not so nicely graphically packaged or indexed on the Ghostbusters wiki.

Gurps All-star jam 2004 (downloadable from Steve Jackson Games for $7.99)
Has a brief but quite well done article on Ghosts and Ghostbusting, all stats therein are for 3rd edition Gurps. I still recommend it,as it nicely adds detail to the Ghost classification system from the Ghostbusters RPG with more on ghost types and the past history of ‘busting in “reality” and fiction. Essential? No, and by no means all inclusive but good and concise. If price is a deal breaker it is available on Amazon.

Haunted Places: The National Directory: Ghostly Abodes, Sacred Sites, Ufo Landings and Other Supernatural locations
by Dennis William Hauk, (usually under a $1.00 on Amazon used or for a ridiculess $14.39 in E-format)
If you are basing your Ghostbusters game in the United States this state by state listing is a cheap and convenient one stop for your locale’s haunted history, at least up to 2002. Think of it as book of story seeds for your game. The same author did an international version of the same book the”The International Directory of Haunted Places ” which is skimpy and doesn’t do any kind of justice to the British Isles, Japan or any of the other countries there in.

Haunted America, Haunted Heartland etc. (available cheaply at Amazon)
By Michael Norman and Beth Scott
Another even more inclusive set of State by State ghost reports. Not as easy to use as the “Haunted Places Directory” but has multiple volumes and has many, many anecdotes. For the price it is a cheap resource for a time constrained GM.

GB Video Game lost entries
These are some of the Tobin’s Spirit Guide entrys of effects and entities that were meant for the GB video Game
But didn’t make the final cut. Maybe they could spark some ideas for GB Gms.

* Will O Wisps

Name: Adhesive Memo Zombies
Desc: I’ve come to call a certain collection of phenomenon the ‘conglomerate
effect’. This is when several smaller, seemingly mindless animated
entities come together and generate a collective intelligence and form a
larger body composed of the smaller parts working in tandem. Most of these
conglomerates have focal points that act as a central nervous system as
well as a weak point. I feel that if one were to disrupt these points, the
being would be forced to disperse.
Note: One of the most peculiar conglomerates I’ve seen is composed solely of
paper. This material doesn’t make for a very effective defense against our
beams, but they are very light and evasive creatures.
Ability: Melee Attack
Tips: Seeing animated objects taking humanoid shape is always a little
unsettling, even when it’s something as relatively harmless as paper. If
you want to trash these guys, use the Blast Stream and burn them down to
their weak points. After that, tearing these apart is as easy as wrangling
and slamming those points.
Class: Class 2 Organic Physical Conglomerate

Name: Avatars
Desc: There are beings in this world I’ve come to call “avatars”. I believe they
are merely puppets that walk this world under control of greater forces.
These forces are fathomless, external beings that seem to choose random
people and play games with them.
Note: I’m not certain what Tobin is talking about in this entry. I do believe
that this account is a precursor to some of his controversial and harder
to find epistemological works where he ponders the “players of the game”
and whether our world even exists when they aren’t watching.

Name: Ghost Hunting Tome
Desc: Any great supernatural investigator will need to equip himself with
every resource at his disposal. This includes a library of books written
by the stalwart hunters of years past. The written word is our best way
to transmit knowlege to future generations of investigators, spreading
the word as far as the printing press reaches. I hope that in writing
this book I have done my part in securing humanity’s future.
Note: With the advent of digital media and the BBS, we can transmit crucial
ghost hunting information across the nation in a matter of minutes.
When it comes to fighting the forces of evil, my work ethic mandates
the dissemenation of information over hoarding and patenting. Peter,
on the other hand…

Name: Gozer
Desc: Gozer was a deity that rose to prominence in Sumeria around 4000 B.C.
He was known as Gozer the Traveler, Gozer the Gozerian and Gozer the
Destructor. During each of his manifestations in the material plane
throughout history he would enter through a portal and choose a form
designated by the worshipers who were present. Sketchy accounts and
records mention his choice of a “Giant Sloar” in one instance and a
“large and moving Torb” in another. I’ve tried to cross reference many
tomes to decipher just what these were and have only been able to
definitively conclude that they were not pleasant things at all.
Note: Despite his impressive shape shifting abilities, Gozer never really
reached a widespread following among Sumerians after his peak in
4000 B.C.E. This potentially angered him and sent him into a brooding and
plotting spiral that we’ve recently seen the repercussions of here in the
20th century.

Name: The Initiate
Desc: Of utmost importance in our profession are the initiates to the craft.
The passion of the newly indoctrinated helps to fuel the jaded
practicioners who’ve seen many years of disappointment and ridicule for
fighting invisible enemies. The enthusiasm of new recruits also helps us
gain new perspectives on our work and ensures our fight will continue to
subsequent generations.
Note: New hires are important for us to expand the Ghostbusters franchise.
Peter sees it mostly as business expansion but Ray and myself agree that
the more of us there are, the safer humanity will be. Unpaid interns were
flaky and ended up costing us more through property damage anyway.

Name: Inter-Dimensional Cross-Rip
Desc: Every so often the world of the abyss spills over into our world through
some event, either intentional or by happenstance. When this occurs
there’s usually an intense amount of energy released as the opposing
dimensions collide, hence the term ‘rip’. There have only been a few of
these recorded in known history, and time the very foundations of our
reality have been threatened.
Note: Having witnessed one of these events firsthand, I can attest to the
intensity Tobin speaks of. In our case the cross-rip occurred through
some form of ritual magic and was closed by an ill-advised experimental
use of our protonic equipment. Reality has been ostensibly preserved,
though I cannot speak for any minor details that might have rippled out
from the eipcenter. It’s entirely possible that a handful of people in a
20 mile radius might have had their identities switched.

Name: Kitchen Conglomerate
Desc: I’ve come to call a certain collection of phenomenon the ‘conglomerate
effect’. This is when several smaller, seemingly mindless animated
entities come together and generate a collective intelligence and form a
larger body composed of the smaller parts working in tandem. Most of these
conglomerates have focal points that act as a central nervous system as
well as a weak point. I feel that if one were to disrupt these points, the
being would be forced to disperse.
Note: I’ve seen one of these form out of cutlery and various pots and pans in a
kitchen setting. The primarily metal composition of this thing made it
particularly dangerous.

Name: Mannequin Wisps
Desc: More powerful spectral manifestations have the ability to not only
levitate objects, but to imbue them with a temporary sense of life.
This is usually done to effigies and statues with discernible body parts,
but more exotic variants have occurred based on the proclivities of the
animator. These creations are usually easy to disrupt and are only a
serious threat in large quantities.
Note: The dismembered mannequins creep me out but believe me, it beats having
real body parts hurled at you.
Ability: Flying Ram
Tips: The Shock Blast is your best choice here, especially when facing several
at once.
Class: Class 4 Psychokinetic Manipulation Event

Name: Marshmallow Hoppers
Desc: Some destructor manifestations of gods have been known to spawn smaller
minions from their bodies. These creatures carry out menial tasks and
terrorize the denizens of an area while the destructor form goes about
its business leveling the architectural structures. They are often weak
and travel in large numbers to overpower their prey.
Note: One of the minion forms spawned from Stay Puft had a cylindrical form
that I swear looked just like giant marshmallows. This is possibly a
psycho-resonant associative pattern imprint carried over from Ray’s
perceived relationship between the Stay Puft character and the
marshmallow confection. Fascinating.
Ability: Suicide Charge
Tips: These critters de-animate once they make contact with a human, but don’t
wait for that; use the Blast Stream to melt them to goo before they can
reach you.
Class: Class 3 Destructor Manifestation Homunculus

Name: Office Wisps
Desc: Often times, in the vicinity of a ghost with strong psychokinetic
abilities, certain small objects will seem to take on a life of their own,
moving at the behest of the controlling spectre. It’s important to make
the distinction between these objects being remotely manipulated and
having an actual spectral presence inside them.
Note: Offices have a lot of small, seemingly harmless implements lying about the
place. This environment makes the perfect haven for a telekinetic ghost,
giving it many places to hide as well as a nigh-endless supply of small
things to fling at its pursuers.
Ability: Flying Ram
Tips: Sweeps of your Blast Stream can take these out rapidly even when spread
out, but if they clump, don’t be afraid to send ’em a Boson Dart and take
them all at once.
Class: Class 2 Psychokinetic Manipulation Event

Name: Phantom Matter
Desc: In areas of high spiritual activity, objects can partially slip across to
the ethereal plane. In most cases some aspect of the object’s physical
properties will remain behind. This can result in an object that is
visible but intangible or invisible but quite solid.
Note: Phantom matter can be quite a nuisance, as there’s no way with our current
technology to alter it. Invisible walls can sit obstructing passage for
years. Ray has been keeping tabs on an intangible toilet in Grand Central
Station that’s claimed many an embarrassed victim.

Name: Protective Psychokinetic Barrier
Desc: A few spectres I’ve dealt with have honed their skills to focus on
personal protection. These entities can generate a barrier of PK energy
to shield themselves from potential disruption. The few times I’ve managed
to breach one of these shields required a high level of energy and
disruptive trauma. In most cases, the collateral damage almost outweighed
the benefit of dealing with the offending manifestation.
Note: Fortunately we’ve developed a variety of means to deliver high levels of
disruptive trauma. The most effective thus far has been the Boson Dart.
It may build up heat quickly, but it takes care of these PK barriers very
effectively.

Name: Psychokinetic Manipulation Event: Museum Implements
Desc: More powerful spectral manifestations have the ability to not only
levitate objects, but to imbue them with a temporary sense of life.
This is usually done to effigies and statues with discernible body parts,
but more exotic variants have occurred based on the proclivities of the
animator. These creations are usually easy to disrupt and are only a
serious threat in large quantities.
Note: A storage room is a good location for a manifestation to find lots of
loose objects to throw around. It’s inconvenient that these are usually
the kinds of places we end up hunting them.

Name: Terror Dogs
Desc: Zuul and Vinz Clortho were minions of Gozer around 4000 BC. Zuul was a
demigod in its own right and had many followers among the Hittites,
Mesopotamians and Sumerians. It is said that should Gozer return to the
world of mortals that these two would herald that return, acting as
key master and gate keeper to consecrate a ritual of sorts that would open
the door to the abyss and let Gozer walk among mankind once more.
Note: Every word in Tobin’s here actually occurred here in New York not that
long ago. He did fail to mention how the terror dogs would first choose
human forms, and that they’d smell like burning animal hair after being
destroyed.

Name: Unassuming Demons
Desc: There are certain paranormal beings I’ve come across that are not
manifestations at all. In fact, these creatures seemed to be flesh and
bone, having walked through some portal leading from their parallel
plane of existence to ours, veritable demons on earth. This is usually the
result of some sort of summoning, and as such these beasts are extremely
hard to get rid of. What little damage I have seen dealt to one seemed to
simply anger the thing, altering its demeanor to an even more terrifying
state.
Note: One of the more unusual ‘demon’ species my associates have encountered was
one that was completely unassuming at first. It exhibited no hostile or
even fleeting behavior upon contact. Once this thing was damaged, however,
it became highly agitated and relentlessly assaulted the team. These
things are best left alone, or if they must be engaged, do so one at a
time.
Ability: Passive Nature, Melee Attack
Tips: These guys prefer to sit and watch the action, but if you accidentally
(or not-so-accidentally) burn them, they’ll come after you in a hurry.
Either leave them alone or make your first hit a good one, such as a
Boson Dart.
Class: Class 3 Demonic Manifestation

Name: Will O Wisps
Desc: Phantom lights are among some of the oldest of witnessed supernatural
events. They’ve been known to lure people off into forests and swamps
where they were never seen or heard from again. I believe these
manifestations are a way for a spectre to affect the physical world with
as little energy as possible. It can then use this minimal effort to lure
in a human victim that it could potentially drain for energy to then
manifest in a more coherent form. I have yet to witness this energy
transfer process.
Note: Most of these occurrences can probably be explained by piezoelectrical
potential built up in certain materials abundant in the areas where the
“will o wisps” have been witnessed. I’m certain there are some cases,
however, where malformed psychokinetic entities wander aimlessly about,
their energy burning off haphazardly as light in the visible spectrum.
