5.6 Notes
It is recommended to make a cost assessment before starting a search:
The cost per connect hour is low in CA, SEARCH terms are charged. When searching E# lists (SELECT or
EXPAND) or when using TRANSFER, high costs may result quickly.
The HCA file has a higher connect hour fee but no SEARCH term pricing. When searching E# lists (SELECT or
EXPAND) or when using TRANSFER, HCA is, therefore, to be recommended.
In ZCA no connect hour charges apply but the SEARCH term fee is higher. The Z-files can be recommended
for browsing E# lists, e.g. the IPC thesaurus.
