   • 1963, “New Physical Research Facilities”, in Major Activities in the Atomic Energy Programs, January–December 1962, United States Atomic Energy Commission, United States Government Printing Office, page 336:

     Seven new elements were discovered with the 60-inch cyclotron: 85 (astatine), 93 (neptunium), 94 (plutonium), 96 (curium), 97 (berkelium), 98 (californium), and 101 (mendeleevium).

   • 1970, O. A. Songina, Rare Metals, page 290:

     In 1960 the following transuranide elements were definitely known to exist (atomic numbers are given in parentheses): neptunium (93); plutonium (94); americium (95); curium (96); berkelium (97); californium (98); einsteinium (99); fermium (100); mendeleevium (101). […] Element 101 — mendeleevium — was prepared in an even smaller quantity: 17 atoms in all.

   • 1977, D. A. Johnson, “Oxidation States of the Lanthanides”, in Advances in Inorganic Chemistry and Radiochemistry, volume 20, Academic Press, →ISBN, section “Extension to Other Systems”, subsection “Actinide Series”, page 110:

     The first dipositive actinide ion to be identified in aqueous solution was that of mendeleevium (262). […] As mendeleevium is the analog of thulium, it was not surprising that nobelium, the analog of ytterbium, was subsequently found to form a very stable dipositive oxidation state.
