Is there a way to merge pdf files?

Question

I have got the cd for my new chemistry book and i have gotten the pdfs off the disc, but the pdfs are all separated by chapters and sections, so there is a different pdf file for the appendix, glossary, index, answers and one for each individual chapter.
When I open each chapter in 'preview' on my mac, it has all these options on the side to skip to certain parts in each chapter, I want these to combine for each chapter.
Thank you.

Answer 1

Free program PDFSAM Basic (Split And Merge) should do what you want.

Answer 2

Preview cannot merge PDFs. Use PDFMergeThing or pdfsam.

Answer 3

Can you highlight the text to copy it to a word file? Also, sometimes you can open it, then save it as a word or .txt file. If you can get it into a text file then you are golden.

Answer 4

I think you can do it. here is a "Jeves PDF Utility" which spit, merge, encrypt many pdf files in to one. its free. please google for the download page.
