You can send us books or solutions that you want to contribute through the form in the contributions section:
. All contributions are published anonymously, but if you want to be mentioned in the publication you can indicate it in the message.
Before submitting the form, please use our search engine to verify whether or not the book or solution you wish to submit is included in our database by typing the author's name or surname in the search engine.
In case you have an existing Book or Solution Book that you would like to contribute (either because you have found an error, or to provide a better version of it), please fill in the form clarifying the modification.
