The tags say this is for 5e, pathfinder, and OSR. Since that doesn't seem to be the case, I recommend clearing that up.

This book makes a lot of interesting promises. Any way to check under the hood and see a little of how it does what it does? Could we see 10 to 20 pages of this almost 300 page book so we can see how it works a bit? Thanks in advance for your response.

Hi Andrew! Sorry, somehow, the preview option got turned off. Thanks for letting us know! We've re-enabled it to show the first 15 pages as usual for our books. This has all the front matter (including the index so you can see all the topics we cover), plus you get the complete sections for Aberrations, Acid, and Air/Fly/Wings.

Many sections run an average of 4-5 pages, each separated into that creature or damage type's misc. traits, followed by actions, followed by reactions, and scaled by creature size when relevant. Some sections are only 2 pages (like Senses), while some are 10 pages (like Humanoids). Hopefully, the preview generates quickly... I'll check back in a bit and see if it's up or if I need to contact customer service.

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
