Title : Ein zahlentheoretische-logarithmischer Rechenstab

Author : Ivan Paasche

It's written in German and was published in "MNU. Der Mathematische und Naturwissenschaftliche Unterricht" 6, 26-28 (1953/54)

It's been cited multiple times, but I'm not able to find this paper anywhere, tried searching over multiple academic databases and search engines but failed.

Issues from this publication are available from 2014 onwards but not for the previous years.

    Chances are that it hasn't been digitised and will only be available by interlibrary loan (which might be done by scanning) from a few libraries in Germany. Jun 1, 2022 at 3:44

    Putting the citation in my local library search finds "Der mathematische und naturwissenschaftliche Unterricht". Older volumes should be available through German university libraries. Jun 1, 2022 at 5:05

    Looks like numerous libraries in Germany have it: zdb-katalog.de/title.xhtml?idn=01116672X Talk to your local librarian.

    This might ultimately make no difference, but in this context "zahlentheoretische-logarithmischer" looks strange to me; I'd expect "zahlentheoretisch-logarithmischer" (with no "e" at the end of the first word). Google finds more occurrences of the former than the latter, but that might result from a single typo propagating through later citations. Another possibility might be "zahlentheoretischer logarithmischer". Jun 1, 2022 at 14:08

1 Answer 1


To look for a paper/publication/book, there is one definitive solution, succesful in 99.9999999% of cases:

  1. ask the librarians.

Maybe you do not want to contact librarians, because you cannot phone them, you cannot write an email, you cannot visit a library, so you are left with performing these 3 steps:

  1. look in the library.
  2. ask the librarians.
  3. ask researchers who cited it (if you can ask other researchers around the world, you should have first contacted a librarian, anywhere in the world).

But it must be stressed that 2) is the solution in 99.9999999% of the cases, because... if you have an issue with your eye, do you google it or do you make an appointment with an ophthalmologist?

An iterative google search may help you, for example searching part of the title, not the complete title and reference, pinpointing which library has the required object in their catalog. However you may still have to contact the library having the desired publication... therefore you save time by asking the librarian and completely skipping the multiple google research, plus the outcome is most likely to be successful (by asking the librarians).

    "improve the answer"??? Add a few more 9's? Anyway, lots of librarians can help, even those not specifically in academic libraries. Even my local village librarian is very helpful since they have many contacts.

    This is what librarians (particularly research librarians) live for. The OP would make their day asking them to track down an obscure paper in an even more obscure journal. It’s like finding the Holy Grail for them.

    You do realize that probably 99.999999% of the ppl here, if they have an eye problem, they google it, right?

    @DonQuiKong since I cannot decide how the 99.999999% of the ppl here waste their time, I can only let them know that before spending time on googling (let's say 20 minutes), the best way is to spend the same amount of time contacting a librarian (2 minutes of unsuccesful googling + 18 minutes to write a proper email to the librarians of choice)
