You have reached the section of books on various topics in PDF format that, although they do not belong to a particular category, are of great interest to today’s society.

This is a dynamic section that is growing over time and in which we take into account the opinion of our readers. They are very different topics from each other, but with a common aspect, they are totally valid and they are in a boom.

We are constantly working on expanding this list. In this collection we are interested in topics from both the scientific and humanities fields. Some of them are quite specific, those that have branched out over time, in relation to the super-specialization that in many cases we see today.

Often, we witness new specializations coming to light, in order to obtain better results in various areas of science or the humanities. However, we do not discard a subject because it is general or, rather, because it touches on general information.

Some are quite peculiar and interesting; such as books on endangered animals or on agriculture. This is to satisfy the needs of thousands of researchers, students or readers who come to us with very particular interests.

We recommend you to review thoroughly these collections of varied topics because maybe there you will find exactly what you have been looking for. Just because they are not categorized does not mean that they are not relevant. And if you are interested in a particular topic that we have not yet developed, just contact us and we will gladly include it in the list.

What topic are you interested in including? Don’t hesitate to tell us, as long as there are books available and in the public domain, we can include any of the ones you can think of. For us there are no good topics, no bad topics, no right or wrong topics, as long as they do not incur in legal problems.

Remember that as it is a dynamic section, some topics are here temporarily, as they will later be included in a new category. This is important to clarify so that you do not think they have been removed from our website.

Finally, we invite you to take a look at our collections of books on various topics and choose the topic of your preference. Our goal is to offer you more options every day and make us your favorite place to study and read.

Well, here ends our collection of books on various topics in PDF format. We hope you liked it and that you already have your next book!
