This is an OPEN-FORUM thread, i.e., anyone can update the last revised set of guidelines.
Welcome to the PGM Forum
Here are some general guidelines for this thread. Remember that grading from a scan is not 100% reliable, but it is fun and interesting. Please contribute any suggestions you may have to these guidelines in this thread.
PGM = "Please Grade My"
GENERAL GUIDELINES
1. Please respect others while participating in the PGM Forum. Critique is valuable, but sometimes it can be over-the-line. Be conscious of what you post.
2. Please post only one (1) book per thread and a maximum of three (3) books per person per day.
3. You may provide a brief description of the book's condition and any hidden defects such as a loose or detached cover or centerfold, spine splits or tears, interior stains or tanning, popped staple, and any other defect that is not readily discernible from a scan.
4. Please provide adequate size scans or, at the very least, clear photos of the book you are submitting for grading. Good quality scans are superior to photos, but if you don't have access to a scanner, photos will do.
5. Post scans of both front and back cover at a minimum. Additional scans or photos of problem areas are often helpful.
6. It's your thread - do as you like. But the recommended size of the scan within the thread is 850x1200 pixels. Anything larger tends to drag out the screen dimensions of the thread. You can link to larger scans if you like, but direct links are better.
7. The recommended file type is .jpeg.
8. Most scanners have a neutral background, but you may want to place a colored backer board or paper behind your book prior to scanning. This may help to accentuate the edges of your book. Be sure that the backer board is not the same or similar color as the general colors of the front or back cover.
9. If you post your book in the PGM forum for grading and eventually send it into CGC for professional grading, it is suggested that you post the CGC results and if possible, an image of the slabbed book. Many here would like to see how well their grading skills match up to those at CGC.
TIPS ON SCANNING
Don't crop the edges of your scans too tight to the book edges and corners.
Allow space around the perimeter of the book.
Many scanners have default settings to select the image on the scanner bed. It is suggested that you turn that feature off.
