Check to see if this is really so by downloading the material and comparing it with yours. If you think the description of the earlier material is incomplete, update it using the Feedback tab. If you disagree with the moderator’s comment, write him about it. We will figure it out.
11. What are the principles applied to determine duplication?
In general, a file added at a later time is considered duplicate, unless it features a version of much better quality.
Duplicates are generally considered to be:
materials of similar formats (e.g.: DOC, DOCX and RTF);
materials in different formats, if the newly added file is a product of the automatic conversion of the previously posted file;
stereotyped editions and reprints (without substantial changes);
separate volumes / parts of a book, if a full archive collection is already available and vice versa.
The following is generally not considered to be duplicates:
materials of different formats (e.g.: DOC, DJVU and PDF);
materials of different publication years.
12. I want to add some material that is already available on the site in better quality. Should I do so?
You should, in the cases as follows:
1. Material’s resolution provides significantly better readability and OCR possibilities. The recommended values are 300 dpi and 400-600 dpi for the small print. Excessive resolution of 1200 dpi is not better for reading than 300 dpi since the difference will not be visible on the display, and the file size will increase by an order of magnitude. 300 dpi is much better than 100 dpi, since all the text-recognition software is optimized for 300 dpi.
2. Important pages were added to the new material. Additional pages with advertisement or covers are not a reason for material replacement.
3. New material features better figures and diagrams.
4. New material features text or OCR layer, if carefully cleaned and proofread. For example, if formulas, diagrams and figures in the text layer were turned into trash, it will not count as improvement.
When adding better quality materials, you should write in the comments to the new file that it is meant for replacement of lower-quality version (+ link to the old material). This will allow to avoid confusion when materials are reviewed by the moderator.
13. I want to add a selection of materials on a topic, a number of different books or one book in several formats in one archive. Is it worth it?
Generally, it is not since:
it makes search more difficult;
it makes more difficult to found duplications;
it deteriorates completeness of description;
it creates problems in replacing a book for a better quality version;
it is not always convenient to download bulky archives;

The following files are normally uploaded as an archive:
parts of a publication (e.g.: parts or chapters of a book, a course of lectures);
books with appendices (e.g.: graphic or audio materials)

14. I want to delete my file. How do I do this?
You need to go to the Mediafiles tab of the console, find the intended file and delete it.
15. My material has passed review. Later I received a message about duplication or remarks regarding formatting. What happened?
The fact that your material has been successfully reviewed does not mean that there may be no questions regarding it in the future.
Please edit the description of your file in accordance with the the moderator’s comments.
