How to extract pages from a pdf file

I have downloaded a pdf file of an open source book and want to extract a chapter relevant to my interests. In LO I seem only ableto open the first page of the document. In the Hathi Trust"library" system in the US and the Gallica site at the Bibliotheque nationale de France, one can select or extract portions of a digitised work . However, in the case of other pdf files, such as several that I have, they have to be opened and managed independently of the originating source. It seemed to me that Libre Office would have an “extraction” function built in? Any help gratefully received

New to the site, I struggled with the tag system ; nothing I used as a tag seemed acceptable. It seemed that I had to use one of several tags listed above the entry point for tags beginning with “common”, so I deleted everything I had used and added “common”. It seems convoluted to a naive user.

In LO I seem only able to open the first page of the document

Please choose View- Page Pane. Now you can navigate by pages, select any of them and Delete Page (from context menu). Then export short version of document as PDF

nothing I used as a tag seemed acceptable.

One problem with this system is that mostly any tag is acceptable. You can add them freely. They are made available to the next user. Tag collection is a mess.

The problem you had is different:

I have gathered (which is not obvious on the start screen): For all questions it is mandatory to use at least one tag to mark which app (Base, Calc, Draw, Impress, Writer) your question is about, “common” if it concerns all apps or the LibreOffice suite in general, or “meta” if it is about this service and not the office suite as such.

I could not understand how to get the document into the view-page pane system . There seems to be no simple way to open a pdf document beyond the first page. For old hands much of this must seem automatic. But even logging on seems to me a problem. I couldn’t find a log on button on the Home page for LibreOffice which seems to be entirely devoted to spruiking the system. Clicking on my question in the email reply brought me back here.

I would use a dedicated application for such operation, not LO.

What OS?

With GNU/Linux, I use PDF Arranger. Under Windows, I use an old version of PDFsam but it seems that PDF Arranger should be good as well.

Yes, I know. But the most useful feature is the visual document composer (together with the reordering). And the latest version offering that is 2.2.4.

Note: I just installed PDF Arranger on my Windows 10 machine and it works like a charm. Will use it instead of PDFsam.

I use a Mac and PDF Arranger downloaded but it didn’t install. Not sure if I did something wrong. I was successful with PDFSam . Many thanks for both suggestions

Excellent.
