第11版ブリタニカ百科事典(1911)全29巻リスト (Read Online) 1911 Encyclopedia Britannica (11th Ed.) 29 Vols. Read-Online [辞書・辞典・事典類]
寒いし花粉症だし外に出る気にならないしひまにまかせて本を並べてみました。Internet Archive で検索すると、11版だけに限っても10種類くらいのさまざまなでどころ（図書館など）の e-text がランダムに並んでいます。コーネル大学所蔵本のe-text は字が薄くボケている感じがして却下、ヴァージニア大学のはページの大きさにデコボコがあるのとやたら重いの（と、どうやらまだ全巻ないらしい）で却下、結果、身元不明 (unknown library) だけれどきれいなのが残るはずが、なぜか全巻そろえられませんでした。しょうがないから1，3，6，8，13，17-19，24，26，27，29――多いｗ――は Internet Archive 自身の contribution を使用（コーネルと似たようなものですが）。このInternet Archive のテクストと、Project Gutenberg の e-text については 英文 Wikipedia の "Encyclopædia Britannica Eleventh Edition" 参照。次の検索と併用すればいいかもしれません。
