# Reference request: Susskind-Glogower original paper

I'm trying to find Susskind and Glogower's original paper,

L. Susskind and J. Glogower. Quantum mechanical phase and time operator. Physics 1 (1964) 49-61

where they propose their exponential and sine-cosine phase operators (i.e. $$\widehat{\textrm{exp}}(i\phi)=\sum_{n=0}^\infty |n\rangle\langle n+1|$$ and friends). This paper has a huge number of citations, both from papers that discuss the formalism directly, as well as papers that deal with other formulations of the quantum phase.

However, the journal it was published in, Physics, was apparently very short-lived (published 164-1968) and it's pretty obscure. More to the point, I've been completely unable to find any official online presence for either the journal (reasonable for a deceased journal) or the paper (Google Scholar points to this and little else). In particular, the journal is very hard to google: search terms like "physics" or "physics journal" obviously don't get you anywhere.

Can anyone point me to an online resource that has this or to a print library (preferably in England) that has it?

Through Google Books I was able to find this, but I can't actually tell if it contains the article. If you type a specific search into the "From inside the book" box, you should be able to find out. From my probings it appears that it does (I searched for "time operator," and the paper title is clearly on the page header). You can also search for other articles that were published in that journal and see if they show up inside the book.

On the left it has a "Find in a library" link which is probably your only bet. Good luck.

Thing is, I cannot even find an archive with the journal contents. The journal title makes it very much difficult to google - what does one look for? "Physics"? "physics journal"? – Emilio Pisanty Apr 12 '12 at 16:34
Actually, the find a library gives results in UK (The British Library and The Cambridge University Library). Look with the librarian at your institution if he can receive a scan through inter-library lending. – Frédéric Grosshans Apr 13 '12 at 10:12
I checked with the British Library and it looks like they do have it. I'll update as soon as I'm able to go. – Emilio Pisanty Apr 13 '12 at 15:40

I finally found the paper, at the British Library.

The journal title, on the cover and on the British Library Catalogue, is "Physics Physique Fizika" (with the latter in Cyrillic on the cover), although all citations are apparently only "Physics".

Searching for Susskind on amr's Google books link confirms that it does contain the paper. Clicking "find a library" refers to WorldCat, which I suspect will give (probably) all the libraries near the user's location that have the journal.
