Perhaps you should try some spelling variations:
"sequential networks. historical studies" » "terrestrial networks. historical studies"
"reference networks. historical survey" » "inference networks. historical survey", "reference works. historical survey", "inference network. historical survey"
"sequence networks. historical survey" » "frequency networks. historical survey", "influence networks. historical survey", "service networks. historical survey"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("sequence networks. historical survey") OR ("reference networks. historical survey"))) OR ("sequential networks. historical studies")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"sequence networks. historical survey\") OR (\"reference networks. historical survey\"))) or (\"sequential networks. historical studies\"))".
• Removing quotes may allow a broader search: (((( sequence networks. historical survey ) OR ( reference networks. historical survey ))) or ( sequential networks. historical studies )).
• Adding a wildcard symbol may retrieve word variants: (((("sequence networks. historical survey") OR ("reference networks. historical survey"))) or ("sequential networks. historical studies"))*.
