start with econlit ? krichel S1 0 KRICHEL We should have a look at the bluesheet html We find authors are not in the basic index.

we can find out about papers written s au=thomas krichel S2 0 AU=THOMAS KRICHEL ? s au=krichel S3 0 AU=KRICHEL ? s au=krichel,thomas S4 0 AU=KRICHEL,THOMAS ? s au=krichel, thomas S5 8 AU=KRICHEL, THOMAS ? s au=krichel, t. S6 0 AU=KRICHEL, T.

turning to RePEc ? b 139 ? s repec S1 38 REPEC ? t s1/k/all ? s (repec/ti) or (repec/ab) or (repec/de) 3 REPEC/TI 10 REPEC/AB 30 REPEC/DE S2 38 (REPEC/TI) OR (REPEC/AB) OR (REPEC/DE)

evaluating The ones that have RePEc in the title and abstract are about RePEc or use it extensively. The ones that have it in the descriptors sometimes have a URL of the form../wider/…/repec/… meaning the information has been made available as part of RePEc. The entries for the copyright are on all EconLit entries that come from RePEc. They are not searchable.

descriptor records ? s (repec/de) not (repec/ti) not (repec/ab) 30 REPEC/DE 27 (REPEC/DE) NOT (REPEC/TI) NOT (REPEC/AB) ? s (repec/de) not (repec/ti) not (repec/ab) not (wider/de) ? s (repec/de) not (repec/ti) not (repec/ab) not (wider/de) S4 0 (REPEC/DE) NOT (REPEC/TI) NOT (REPEC/AB) NOT (WIDER/DE)

first set The 3 papers that have RePEc in the title talk about RePEc. The 8 that have RePEc in the abstract but not in the title use RePEc. We put those into a latter part of our written report to the patron. There are probably more papers that use RePEc but the use has not been reported.

finding the right krichel ? s krichel S1 15 KRICHEL ? t s1/k/all Manual inspection reveals that all the records that relate to the patron either are – krichel(N)thomas – krichel(N)t – tkrichel(N)openlib ? s krichel(N)thomas or krichel(N)t or tkrichel(N)openlib We get 13 records that deal with the patron in different ways, it is prudent to add all to the report.

move on to RePEc ? s repec not (krichel(N)thomas or krichel(N)t or krichel(N)openlib) 111 REPEC 107 REPEC NOT (KRICHEL(N)THOMAS OR KRICHEL(N)T OR KRICHEL(N)OPENLIB) How to filter this?

filtering URLs First, kwic inspection reveals that a lot of records have URLs of the form ? s s1 not (http(N)ideas(N)repec(n)org) 107 S HTTP IDEAS 111 REPEC ORG 46 HTTP(N)IDEAS(N)REPEC(N)ORG S3 61 S1 NOT (HTTP(N)IDEAS(N)REPEC(N)ORG)

better filtering There are some URLs that have a RePEc in the URL as part of the path, so s s9 not (http(5N)repec(N)org or edu(2N)repec not au=krichel t) When looking at this, there are about half the papers that appear to be relevant, but I have not been able to find a clever filter for those.
